Mixture-model typo in FLUENT6.2 documentation?
Hello. Regarding FLUENT's mixture model: Equation 24.3-11 defines the relationship between drift-velocity, MASS FRACTION and relative velocity.
The document in FLUENT's Bibliography (Manninen et al.) defines drift velocity as "the velocity of the dispersed phase relative to that of the volume centre of a mixture" (p.20). Manninen also defines diffusion velocity as "the velocity of phase k relative to the centre of the mixture mass" (p.18). In Manninen (p.20) they define the relationship between drift-velocity, VOLUME FRACTION and relative velocity.
According to Manninen it appears as if FLUENT is using a diffusion velocity equation and presenting it as the definition for drift-velocity.

Due to lack of respones I am giving the link to Manninen et al. It can be found at:
